If you read the fine-print on any Bill of Lading, underneath the line where you're signing, you will discover that you are basically signing your life away... i.e. you are stating that you received the goods in acceptable condition, and you are absolving the trucking company of any further responsibility. You're on your own once you sign.
So.... Do all you reasonably can to never sign without inspecting the products themselves. I've seen plenty of horrendous damage inflicted to panels in cases where the outer box still looks perfect. We (NPD) always carefully inspect the panels in our shipping department before we pack and ship. We do it for your best interests (to avoid shipping you anything that was damaged from the factory), and we do it to protect ourselves as well. Because you cannot imagine how many people just look at the box, say "seems fine to me", sign for the shipment without reading what they're signing, and then once the driver is gone they open the box to discover hidden damage.
The truck driver cannot leave unless you sign, and he cannot "force" you to sign before you've inspected.
And yes, I get it, if you're talking about a substantial crate or something that takes considerable time to unpack, it's natural that some drivers (especially if they've got a packed day of deliveries) will have ants in their pants.
You've just gotta realize that once you sign, you've pretty much signed away any possibility of going after the trucking company, and it's just between you and the supplier. And the supplier will not be "pleased" that you signed without inspecting, because your failure to take the time to inspect now becomes their problem. A problem that should have been avoidable.
Below is a photo of the bright day-glo label we apply to every truck-freight order, and then I backed up to show all of the various labels, warnings and threats that we apply to every truck-freight box LOL... If we could, we'd ship an elf with ever shipment to make sure every handler along the way took heed of our instructions and handled the box correctly!
